Abstract: A cutting guide apparatus for guiding placement of bore holes in a door may include an engagement interface and a backset assembly. The engagement interface is configured to retain the apparatus proximate to an edge of a door and center an edge bore guide between an inside face and an outside face of the door. The engagement interface includes a first arm and a second arm that are each operably coupled to a common pivot axis. The backset assembly is operably coupled to the engagement interface to enable an amount of backset from the edge of the door to a center of a handle hole guide to be adjusted. The backset assembly includes a first mounting bracket operably coupled to a first portion of the first arm and a first portion of the second arm, and a second mounting bracket operably coupled to a second portion of the first arm.

Abstract: An example cordless portable power drill is provided. The drill may include a drill chassis, and a spindle mounted to the drill chassis. The spindle may be configured to drive a working bit. The drill may also include an exit port configured to direct a flow of a substance towards the working bit and an electric motor mounted to the drill chassis and operably configured to rotate the spindle. The drill may also include a pump mounted to the drill chassis. The pump may be fluidly coupled to the exit port, and the pump may be configured to pressurize the substance for output via the exit port to cool the working bit or remove debris created by the working bit through interaction with a workpiece.

Abstract: Feed tools and methods of use for initiating a change in a spindle feed direction from an advance direction that moves the spindle towards a workpiece to a retract direction that moves the spindle away from the workpiece. The tool and methods may use a thrust overload force that is generated on one or more of the components to initiate the shift from forward to retract and/or a lift ring that acts on one or more of the components. The tool and methods may also include a two-stage piston to accomplish the shift. The various components may be used independently or in combination within the tool.

Abstract: Positive feed tools and methods of use that include a spindle with a distal end configured to receive a tool bit. The spindle is movable in a forward direction for the tool bit to act on a workpiece, and a retract direction to move the tool bit away from the workpiece. The spindle is configured to retract to a home position at which an air motor that drives the spindle is shut off. The feed tool includes a clutch to prevent jamming of the spindle at the home position in the event the air motor is not shut off at the proper time.

Abstract: A positive feed tool that includes a spindle that is axially moved along a feed path to perform work on a workpiece. The tool includes a gear head with a plurality of gears configured to rotate and axially move the spindle. The gear head is designed to change the changing gears within the gear head to change feed rates on the spindle. The gears can be interchanged without a complete disassembly of the gear head.
